1MZFE, 116K. The car has always (since I got it a year ago w 96K on odo.) run up to 1600-1700 rpm from a cold start, then drops to 700-750 rpm when warmed up completely. Obviously, in the winter this takes a while. TB kit recently done with no change. Otherwise, she runs smooth, quiet and strong, no codes or CEL. Any suggestions as to where to start? And thanks!

Normal. The quicker the engine warms up, the lower the emmissions will be and the better the fuel economy will be. Not to mentioned hot air at the vents sooner as well. Clean your IAC anyhow if you haven't done so and drive it.

Not sure about what the actual spec is, but my 97 ES300 cold idles @ 1700ish or so and slowly idles down. I would say it's normal.

One thing I noticed on mine is that when I start the car in the morning it obviously idles higher just as its supposed to, but I back out of the garage then when I get on the street and put it in drive I get a more than normal jolt going into drive. Sometimes it really jolts you enough to where your head moves lol. Obviously any other time you do this its perfectly smooth. Anyone elses car do this?
